Case Study 2 — A Hydropower Plant

First published 26 Aug 2026 · Last verified 29 Aug 2026

Sabina Thapa opened her notebook to a fresh page and, out of habit, wrote the date at the top before crossing it out and writing today's date instead: August 25, 2026. She almost didn't notice the coincidence until she typed the ticker she had chosen for this case study — CHCL, Chilime Hydropower Company Limited — into her broker's terminal and the company profile line read: commissioned August 25, 2003. Twenty-three years to the day. She sat back in her chair in Kathmandu and allowed herself a small smile. It felt like a sign, though she knew better than to let a coincidence do any analytical work for her. In Chapter 83 she had taken the Canon Score — the book's 100-point, seven-dimension framework for scoring a NEPSE-listed company — and applied it start to finish to a commercial bank. That case had taught her to read a balance sheet full of loans and deposits, to weigh capital adequacy against loan growth, to treat thousands of small, similar transactions as the unit of analysis. Now she was staring at something almost the opposite: one river, one plant, one buyer, and a business whose entire personality was shaped by monsoon clouds and glacial snowmelt rather than by interest rate cycles and credit committees.

That contrast is the entire point of this chapter. A hydropower company is not a smaller, simpler version of a bank. It is a different species of business, and the same Canon Score framework has to be applied with different instincts and different sector adjustments — exactly the kind of sector-specific calibration this book asked you to build in Chapter 65, and exactly the kind of humility about the score's limits this book asked you to practice in Chapter 80. Sabina's task in this chapter is to run Chilime Hydropower Company through the full Canon Score, dimension by dimension, using real, current numbers, and to show her working — including the places where a hydropower company genuinely resists being reduced to a single tidy number.

Lesson 84.1 — Setting Up the Case: One River, One Buyer, One Number

Chilime Hydropower Company Limited, traded on the Nepal Stock Exchange under the symbol CHCL, owns and operates a 22.1 megawatt (MW) run-of-river hydropower plant on the Chilime Khola in Rasuwa district, roughly 133 kilometers north of Kathmandu near the Nepal-Tibet border. A megawatt (MW) is a unit of generating capacity — think of it as the maximum rate at which a plant can produce electricity at full throttle, the way a car's horsepower rating describes its maximum output rather than what it actually uses on an ordinary drive. The Chilime plant uses two Pelton turbines (a type of water turbine well suited to Nepal's steep, fast-flowing rivers) and has been generating power since its commissioning on August 25, 2003. It typically produces around 150 gigawatt-hours (GWh) of electricity a year — a gigawatt-hour is simply a thousand megawatt-hours, a measure of energy actually delivered over time, as opposed to MW, which measures capacity at an instant.

Nepal Electricity Authority (NEA), the state-owned electric utility that is effectively the only legal buyer of wholesale electricity in Nepal, owns 51 percent of Chilime Hydropower Company, with the remaining 49 percent held by the public — including a 10 percent slice specifically reserved for local residents of Rasuwa, the district where the plant sits. Chilime sells essentially all of its output to NEA under a long-term Power Purchase Agreement, or PPA — a contract that locks in the price NEA pays per unit of electricity for a period of years, in exchange for the hydropower company committing to deliver its output reliably. Since its original IPO, Chilime has also become an investor in two much larger plants nearby: Rasuwagadhi Hydropower (111 MW) and Sanjen Hydropower (14.8 MW), both of which began commercial generation in 2024 after years of delay, including damage sustained during the 2015 earthquake. This matters for the case study, because it means the listed company Sabina is scoring is not quite a single, isolated asset — it is a legacy plant plus a growing ownership stake in newer capacity, which changes the concentration-risk conversation this chapter will return to.

Chapter 72 drew a hard line between two fundamentally different hydropower asset classes: pre-COD and operating. COD stands for commercial operation date — the day a plant is certified ready and legally allowed to start selling power under its PPA. A pre-COD hydropower company is still building; its risks are construction risk, financing risk, and the risk that the project never reaches COD at all, or reaches it years late and over budget. An operating company like Chilime, twenty-three years past COD, carries almost none of that risk. Its plant is built, tested, and has a two-decade operating history. This is the single most important qualitative fact Sabina had to establish before she touched a single number on the Canon Score.

That single distinction reframes everything else. A bank's revenue comes from thousands of individual loans, deposits, and fee-generating relationships, spread across sectors and borrowers — genuinely diversified, but also genuinely uncertain, since any of those loans could sour and interest rates could move against the bank at any time. Chilime's revenue, by contrast, comes from one contractually fixed tariff schedule paid by one counterparty, NEA, for as long as the PPA runs. In a good monsoon year, the plant generates close to its physical maximum and NEA pays a known price for every unit. In a bad year, the water simply isn't there, but the price per unit doesn't change — the risk is in volume, not price. Sabina wrote in her notebook: "A bank's risk is who owes me money and whether they'll pay it back. A hydropower plant's risk is whether the sky and the glaciers cooperate — the buyer isn't going anywhere, and the price is already agreed." That is a much narrower, more predictable form of revenue risk than a bank carries — but it comes bundled with something a bank almost never has: the entire business sitting inside a single physical structure, on a single river, that cannot be moved, duplicated, or hedged if something goes badly wrong with that one location.

Lesson 84.2 — Hemisphere 1: Governance, Tradability, and Durability

Sabina followed Sushmita's method from Chapter 83 exactly: split Chapter 64's seven dimensions into the two hemispheres Lesson 83.2 introduced. Hemisphere 1 covers the qualitative dimensions — Liquidity & Tradability (10 points), Governance & Promoter Behaviour (15 points), and Sector & Business Model Durability (15 points), 40 points in total. Hemisphere 2 covers the three dimensions built from the financial statements. She worked Hemisphere 1 first, same as before: if a stock cannot actually be traded and its owners cannot be trusted, the numbers barely matter.

Liquidity & Tradability (10 points). Chapter 65's hydropower guidance is explicit that this dimension needs real scrutiny for thin-float counters, reconnecting it to Chapter 58's circuit-trap warning: a stock can look "liquid" by rising to its daily circuit limit for several sessions while almost no real volume actually clears, leaving sellers unable to exit. On the day Sabina pulled CHCL's data, the session traded just under 19,000 units at a price near Rs 478 — a single day's print rather than the 6-month average Chapter 64 actually asks for, a limitation she noted honestly rather than pretending one day's volume settles the question. Taken as a rough proxy, that print implies roughly Rs 90 lakh (about NPR 9 million) of same-day turnover, comfortably above Chapter 64's NPR 5 million top band, worth a provisional 5 out of 5 on the volume sub-component. Just as importantly, CHCL's 52-week range of roughly Rs 450 to Rs 525 — a band of about 16 percent — moves in both directions over the year rather than sitting pinned at one circuit limit, which is exactly the kind of two-way price action Chapter 65 says to check for before trusting a stock's apparent liquidity. Free float is a tighter fit: with NEA holding a fixed 51 percent stake and 10 percent reserved for local Rasuwa shareholders who tend to hold rather than trade, only about 39 percent of Chilime's roughly 94.8 million shares are genuinely free-floating — just under Chapter 64's 40 percent threshold for full marks, landing instead in the next band down, worth 3 out of 5. Liquidity & Tradability: 5 + 3 = 8 out of 10.

Governance & Promoter Behaviour (15 points). Chapter 65 flags this as a lighter adjustment for hydropower than for banks or microfinance — the standard checklist mostly applies — but Chilime has one structural wrinkle worth naming plainly: its majority shareholder, NEA, is also its sole customer under the PPA. Promoter shareholding stability and pledging (6 points) scores cleanly here — NEA's 51 percent stake has been stable for decades with no evidence of pledging, and the 10 percent locally reserved tranche is a stabilising, not a destabilizing, feature — a full 6 out of 6. Related-party transactions and audit opinion (5 points) is where the buyer-owner overlap actually belongs: a wholly independent hydropower company negotiates its PPA tariff at arm's length, while a NEA-majority-owned company negotiating with NEA itself has less obvious separation between the two sides of that contract, and Nepali hydropower more broadly carries a well-documented history of related-party risk around engineering, procurement, and construction (EPC) contractors. Chilime's own equity-stake projects, Rasuwagadhi and Sanjen, both ran years behind schedule, partly due to 2015 earthquake damage — a disclosed delay rather than a concealed one, but still worth a discount. Sabina scored this sub-component 3 out of 5. Disclosure timeliness and board independence (4 points) — Chilime has filed quarterly results on a regular cadence for two decades, including its most recent quarters, which supports on-time disclosure, but Sabina did not separately verify board independence against the regulatory minimum, so she scored this sub-component 3 out of 4 rather than a full mark. Governance & Promoter Behaviour: 6 + 3 + 3 = 12 out of 15.

Sector & Business Model Durability (15 points). Chapter 64's own worked example names "a hydropower company with a signed PPA" as the textbook case for full marks on the moat sub-component (8 points), and Chilime fits it exactly: a licensed river reach that cannot be duplicated, a signed, long-standing PPA with NEA, and twenty-three years of operating history behind it. Moat: 8 out of 8. Revenue concentration (7 points) is more awkward than it looks. Chapter 64 itself flags, in its own case-in-point callout, that virtually every Nepali run-of-river hydropower company sells effectively all of its output to the single buyer, NEA — and says Chapter 65 exists to fix mismatches like this one. In practice, Chapter 65's sector table only marks this dimension "Moderate" for hydropower, without spelling out a specific numeric fix for the single-buyer structure it promised to address. Sabina's honest judgment call was to treat single-buyer concentration as a sector-wide feature rather than a Chilime-specific red flag — every hydropower peer has the same buyer — while still not awarding full marks, since it remains a genuine, structural dependency on one counterparty and one national grid operator's solvency. She scored it 4 out of 7, noting the partial diversification benefit of now holding stakes across three separate river systems (the original Chilime plant, Rasuwagadhi, and Sanjen) rather than one. Sector & Business Model Durability: 8 + 4 = 12 out of 15.

Lesson 84.3 — Hemisphere 2: What the Numbers Actually Say

With Hemisphere 1 assessed, Sabina turned to the quantitative half of the Canon Score: Financial Strength & Profitability (20 points), Valuation Reasonableness (15 points), Growth Trajectory (15 points), and Dividend & Capital Return Discipline (10 points), 60 points in total — read, throughout, using Chapter 65's instruction to compare same-quarter figures year over year rather than sequential quarters, since a run-of-river plant's output swings sharply between the monsoon and dry seasons for reasons that have nothing to do with the underlying business getting better or worse.

Financial Strength & Profitability. Chapter 64's sub-component A scores a 3-year average ROE. Chilime's most recently reported ROE sits at roughly 6.7 percent, close to its 10-year median of about 7.2 percent, and its 3-year average — pulled down by a trough near 3.4 percent a couple of years ago before a partial recovery — lands below the 7 percent line Chapter 64 uses as its lowest band cutoff. Read literally, on Chapter 64's generic bands, that scores 1 out of 8. Lesson 84.4 returns to this number, because Sabina was not convinced the literal score told the whole story on its own. Sub-component B, capital adequacy or leverage discipline (7 points), uses the non-bank version of this test for a company like Chilime: Debt-to-Equity and interest coverage rather than CAR. At the parent level, Chilime's own balance sheet is close to unlevered — a net margin above two-thirds of revenue paired with an equity-to-assets ratio near one suggests debt-to-equity comfortably under 1.0x and very high interest coverage, which clears Chapter 64's top band for full marks. But this is a parent-level reading only: the real project debt sits inside the Rasuwagadhi and Sanjen investments, which are equity-accounted stakes rather than fully consolidated subsidiaries, so Chilime's own D/E ratio simply does not capture that leverage the way a full consolidation would. Sabina scored the literal, parent-level number at 7 out of 7, flagging the equity-stake caveat explicitly rather than silently assuming it away. Sub-component C, earnings quality and consistency (5 points), reflects a genuinely mixed recent record: quarterly profit and EPS have moved in both directions year over year across the last few fiscal years — a real decline in one recent year alongside modest growth in another — without any outright loss year. That fits Chapter 64's "one loss year, or two flat/declining years" band, worth 3 out of 5. Financial Strength & Profitability: 1 + 7 + 3 = 11 out of 20.

Valuation Reasonableness (15 points). Chilime trades around Rs 478 per share against recent per-share earnings near Rs 7.6 and a book value per share near Rs 125 — a price-to-earnings ratio near 63 times and a price-to-book ratio near 3.8 times. Nepal's hydropower sector has, at different points, been reported anywhere from a sector-average P/E in the high teens to broadly "trading rich" alongside most non-bank NEPSE sectors, well above banking's roughly 15-16x — a real range Sabina could not narrow to one clean number, so she treated the wider end as the more conservative comparison. Even using the more generous high-teens anchor, CHCL's ~63x P/E works out to roughly three times the sector median, deep in Chapter 64's "above 1.5x sector median" band — 1 out of 8. Its P/B of about 3.8x, checked against NEPSE's whole-exchange average of roughly 2.8x (a hydropower-specific P/B median was not something Sabina could pin down cleanly, a sourcing gap worth naming rather than hiding), works out to roughly 1.4 times that broader benchmark — Chapter 64's 1.1x-1.5x band, worth 3 out of 7. Valuation Reasonableness: 1 + 3 = 4 out of 15 — Chilime's weakest dimension by a wide margin, and a real, current finding rather than a comfortable one: on both major yardsticks, the stock is priced well above what its own earnings and book value would suggest, however the comparison is drawn.

Growth Trajectory (15 points). Revenue CAGR (8 points) at the original 22.1 MW plant has been modest — recent quarterly power-sales growth in the low single digits year over year — consistent with a mature, physically capacity-constrained run-of-river asset with little organic room left to grow on its own. The real growth story sits in the 2024-commissioned Rasuwagadhi and Sanjen stakes, whose earnings contribution is only just beginning to show up in consolidated results and has not yet had time to appear in a multi-year revenue trend. Sabina scored this sub-component 3 out of 8, in the "0%-8%" band, while flagging the new capacity as the genuine forward catalyst this trailing figure cannot yet see. Earnings consistency (7 points) reads more concerning on the numbers she could actually check: EPS has fallen year over year in more than one recent quarter, a real decline rather than a seasonal illusion, since the comparisons were same-quarter-to-same-quarter rather than sequential. Without a full, verified 5-year EPS series in hand, Sabina scored this conservatively at 2 out of 7 rather than the lowest band, flagging that a complete year-by-year record might move this figure in either direction. Growth Trajectory: 3 + 2 = 5 out of 15 — Chilime's second-weakest dimension, and one the original capacity-expansion story in Lesson 84.1 does not fully redeem, at least not yet in the trailing numbers.

Dividend & Capital Return Discipline (10 points). Chilime has paid a distribution every year for as long as Sabina could find record of: 8 percent bonus shares plus 4 percent cash for fiscal year 2081/82, down from a 12 percent distribution the year before, and as high as 15 percent in earlier years. The cash component alone, against recent EPS near Rs 7.6, works out to a payout ratio in the neighbourhood of 50 percent of earnings — squarely inside Chapter 64's 30-70 percent sensible band, paid every single year: 6 out of 6. The declining trend looks, on inspection, like conservative capital allocation rather than distress — retained cash has visibly gone into funding the Rasuwagadhi and Sanjen stakes rather than disappearing, and Sabina found no sign the payout was propped up by drawing down reserves or a one-off gain: 4 out of 4. Dividend & Capital Return Discipline: 6 + 4 = 10 out of 10 — Chilime's strongest dimension, and its clearest sign of a management team sharing profit with shareholders on a predictable schedule even while investing for growth.

Put together, Chilime's Hemisphere 2 picture is a mature, disciplined operator with an almost debt-free parent balance sheet and an unbroken dividend record, but a stock priced well above what its own earnings and book value currently support, and a growth story that exists mainly in recently commissioned capacity that has not yet worked its way into the trailing numbers.

Lesson 84.4 — Reading Return on Equity Like a Utility, Not a Bank

Chapter 64's ROE bands were built and calibrated around Nepali commercial banks — a 15 percent-plus top band, a 7-to-10 percent "near system average" band, and so on. Applying that same ruler to Chilime literally, the way Lesson 84.3 just did, gives a 3-year average ROE below 7 percent a score of 1 out of 8 — the lowest band the rubric has. Sabina's instinct was that this felt too harsh, for a reason Chapter 65 explains in the abstract but does not spell out specifically for hydropower ROE: a capital-intensive utility with a huge asset base and a large, mostly depreciated plant sitting on its books will structurally show a lower return on equity than a bank or a trading company, even when it is a genuinely well-run business earning a very healthy margin on every rupee of revenue.

Rather than quietly bump the number up, Sabina did what Sushmita had done with Nabil's capital adequacy ratio in Lesson 83.4: she kept the literal score and built a peer table to see what it actually meant in context.

Read against Chapter 64's bank-calibrated bands alone, 6.7 percent looks weak. Read against its own sector — a sector where the disclosed median sits near 3.6 percent, where a well-regarded peer like Sanima Mai sits below Chilime, and where a heavily project-financed peer like Upper Tamakoshi is posting a negative return on equity because financing costs are consuming operating profit before it ever reaches shareholders — Chilime's 6.7 percent looks like one of the stronger returns among genuine hydropower peers, not a weak one. That is exactly the pattern Chapter 65 warns about in the abstract: a generic ratio measuring the wrong thing when the business model itself is unusual. Sabina left the literal 1-out-of-8 score standing in her tally, on the same discipline Sushmita modelled in Chapter 83 — the peer table changes what the number means, not the number itself — but she wrote a clear note next to it: "Do not read this sub-score as 'Chilime is a weak business.' Read it as 'the bank-built ruler under-measures every hydropower company, and Chilime still comes out ahead of its own peers on it.'"

Lesson 84.5 — The Full Worked Canon Score

With both hemispheres assessed and the ROE context applied without changing the arithmetic, Sabina assembled her full tally, using exactly the seven dimensions and point weights Chapter 64 defines.

Summed, Chilime's Canon Score comes to 62 out of 100 — inside Chapter 64's Adequate band (55-69), a rung above Weak/Avoid and two rungs below Exceptional. No dimension triggers Chapter 64's governance override, since Governance & Promoter Behaviour scored 12 out of 15, comfortably above the 5-point floor that would cap the whole score regardless of everything else.

Sabina was honest with herself about which sub-scores were the hardest calls, and a careful analyst working the same facts could reasonably land a few points differently on any of them. Three stood out. Valuation Reasonableness depended on which hydropower sector-median P/E she trusted, and different sources genuinely disagreed by a wide margin — she used the more conservative anchor and said so, but a reader with a firmer, more current sector figure could reasonably shift this dimension a point or two in either direction. Sector & Business Model Durability's revenue-concentration sub-score was a genuine judgment call precisely because Chapter 65 promised a hydropower-specific fix for the single-buyer problem and did not fully deliver one in its own text — Sabina's 4 out of 7 reflects a reasoned middle path, not a number the rubric handed her cleanly. And Growth Trajectory's earnings-consistency sub-score was scored conservatively, at 2 out of 7, precisely because she did not have a complete, verified 5-year EPS series in hand — a fuller record could move this dimension in either direction once someone pulls it.

Lesson 84.6 — Scale Is Not Quality: Chilime Against Nepal’s Largest Plant

Sabina closed her Chilime worksheet with a question she had been avoiding. Chilime is a 22.1 MW plant. Nepal’s largest is the 456 MW Upper Tamakoshi Hydroelectric Project in Dolakha, listed on NEPSE as UPPER — more than twenty times the installed capacity, a national-pride project financed entirely with domestic money, sponsored by the state utility itself. If size and prestige translate into investment quality, Upper Tamakoshi should score well above Chilime. Chapter 91 works that company end to end. It scores 45 out of 100.

Seventeen points below the small plant, and in Chapter 64’s Weak/Avoid band rather than Adequate. That gap is worth sitting with, because it is the single clearest demonstration in this book of why the Canon Score refuses to collapse into one impression of “good company.”

Read the table across rather than down. On four of the seven dimensions the two companies score identically or near-identically: both are single-asset operators selling to one buyer, so Durability is 12 for each; both face the same hard growth ceiling once commissioned, so Growth is 5 for each; both carry the hydropower sector’s sentiment premium, so Valuation is 4 for each. Governance and Liquidity differ by a single point. The structural business is, in scoring terms, almost the same business at both scales.

The entire seventeen-point gap comes from two dimensions, and both describe the same underlying fact: how the plant was paid for.

Dividend Discipline: 10 versus 1

This is the widest single gap in the comparison, and the most revealing. Chilime has paid every year, funded from genuine operating profit, with a cash component near half of earnings per share. Upper Tamakoshi has not distributed a single cash or bonus dividend to public shareholders in the five years since the plant was commissioned — verified against NEPSE data providers in August 2026, all of which return an empty dividend history for the ticker. Its only shareholder action has been the opposite of a payout: a 1:1 rights issue in FY2080/81 that asked shareholders for more money. A retail investor who bought UPPER expecting a utility’s income stream has, so far, received nothing at all — and Chapter 64 scores what a company has actually done, not what its size suggests it ought to be able to do.

Financial Strength: 11 versus 5

Upper Tamakoshi posted losses for four consecutive fiscal years after commissioning, because interest on its construction debt consumed operating profit before it reached shareholders. Chapter 32 traces the arithmetic: roughly NPR 24 billion of capitalised interest sat on top of a roughly NPR 52 billion construction cost, against an originally approved budget near NPR 35 billion. The plant generates the electricity its engineers promised. It is the financing, not the engineering, that the score is punishing.

There is a mechanical detail in Upper Tamakoshi’s Power Purchase Agreement worth carrying to any hydropower analysis: the plant is designed for a discharge of 66 cubic metres per second and is contractually required to shut down when river flow exceeds 250. During the September 2024 event, flow at the dam site reached roughly 461. A run-of-river plant can be stopped not only by too little water but by far too much of it, and the PPA itself specifies the threshold. That is a modellable risk, and most retail models never model it.

The lesson generalises past hydropower. A larger company is not a safer one; a nationally important asset is not automatically a good holding; and a plant that produces twenty times the electricity can be a materially worse investment than a small one that has paid its debts and shares its profits. The full Upper Tamakoshi analysis — the earthquake, the decade of delay, the interest-during-construction mechanism, and each of the seven sub-scores — is Chapter 91.

Lesson 84.7 — The Decision, and What Would Change It

A score of 62 out of 100 sits inside Chapter 64's Adequate band — investable, per the book's own definition of that band, but sized carefully and watched closely on its weak dimensions, a rung below Strong and two rungs below Exceptional. Reading the seven sub-scores rather than stopping at the total tells the real story: Chilime is comfortably strong on Dividend discipline and Sector Durability, respectably placed on Governance and Liquidity, and dragged down by two dimensions working together — Valuation Reasonableness at 4 out of 15 and Growth Trajectory at 5 out of 15 — with Financial Strength held back mainly by an ROE sub-score that the Lesson 84.4 peer table suggests is measuring the whole sector's structural profile as much as anything Chilime-specific. Sabina's honest conclusion, working purely through the process: Chilime is a mature, well-run, dividend-disciplined hydropower company trading at a price that has run well ahead of both its current earnings and its trailing growth, with real new capacity in Rasuwagadhi and Sanjen that has not yet shown up in the numbers that matter for scoring. That combination argues for patience rather than either enthusiasm or alarm — a name worth watching for the new capacity's earnings to actually appear in trailing figures, or for the price to settle toward what the current fundamentals support, rather than a name to chase at the present valuation or to write off entirely.

What would move this score? Sabina named four concrete, watchable developments. First, and most directly within her control to check, the next few quarters' consolidated results actually showing Rasuwagadhi and Sanjen's earnings contribution flowing through — this would be the clearest test of whether Growth Trajectory's low score is a genuine trailing-data lag or something more persistent, and it is the single change most likely to move Chilime materially up the band. Second, either a price correction toward the sector's actual valuation anchor or several years of EPS growth catching up to the current price would resolve Valuation Reasonableness's weak score one way or the other. Third, the royalty step-up dates already calendared for Rasuwagadhi and Sanjen in the late 2030s, and a PPA renewal whenever Chilime's own agreement approaches its end, remain known, schedulable events worth a standing calendar entry rather than a surprise. Fourth, a genuinely bad drought year — an unusually weak monsoon — would test generation and near-term cash flow directly, though a single weak year would not by itself change the plant's decades-long average flow profile.

Sabina closed her notebook feeling that this case study had taught her something Chapter 83 could not have: that applying the same seven-dimension framework honestly sometimes means admitting a sector-adjustment chapter did not fully deliver what it promised, building your own peer context where the rubric's literal bands mismeasure a business model, and still landing on a number you can defend line by line. A score is only as trustworthy as the analyst's honesty about where it came from.
